AUTOMOBILE COLLISION BUMPER.

Application led January This invention relates to automobile collision bumpers and has for its object the provision ot a bumper which is inexpensive to manufacture and which is exceptionally strong in construction. in one desirable arrangement the bump-er is made of two substantially identical parts which together torni a pair of vertically spaced impact bars adapted to extend across the end of an automobile. The opposite ends ot each ot these bars are bent rearwardly and inwardly and vertically7V one ot the ends being,l consider ably longer than the other and additionally bent forward against the rear ot the impact portions. The shorter end ot each of the bars is secured directly to the longer end oit the opposite bar, and the two longer end portions are brought together at the baclr ot the impact portions of the two bars and connected together and to t-he impact portions by a suitable clamp.

The above and other desirable details oit construction will be apparent from the tollowing' description Vof one illustrative embodiment shown in the accompanying drawings, in which:

Figure 1 is a top plan View of the bumper; and

Figure 2 is a rear elevation ot the bumper with Athe supporting brackets or clamps removed. l Y i The bumper comprises generally upper and lower vertically spaced substantially parallel impact bars l0 and 12 adapted to extend across one end oit an automobile ln the particular arrangement shown in tlie drawines t-he bar 1() is bent rearwardly and inwardly and then Yforwardly to .torni a. relatively longer looped vend portion lll tcrminating substantially in the plane ot and between the impact portions' and there bent in the form of a hook 16. Atits opposite end the bar 10 is bent rearwardly and inwardly and downwardly to form a relatively short end extension 18.

yThe bar 12 is, in effect, liltethe bar 10 except that itis reversed with respect there 30, 1925. Serial No. 5,776.

to. That is, the right end ot the bar 12 bent rearwardly and inwardly land upwardly, and then forwardly to form a relatively longer looped end portion 20 terminating in a hook 22 adjacent the hook 16.` A channel member 24 engaging the hooks 16 and 22, together with a front plate 26 and a bolt 28, Vterms a clamp securing` the ends of the looped portions 14 and 2O to each other and to the impact portions of the bars. The opposite end ot the bar 12 is bent rearwardly and inwardly and upwardly to form a relatively short end extension 3() secured by a bolt 32 to the looped portion 14- of the bar 1()` and the end extension 18 similarly secured by a bolt 34; to the loop portion 2() ot the bar' 12. The bumper as a whole may be supported on an automobile chassis by rsuitable brackets or clamps 36 and 38.

-lVhile one illustrative embodiment ot the invention has been described in netail, it. is not my intention to limit its scope to that particular embodiment, or otherwise than by the terms ot the appended claim.

I claim:

An automobile collision bumper comprisinfn` yvertically spaced substantially parallel impact bars adapted to extend across one end of an automobile, the ends ot' the upper bar being bent rearwardly and inwardly and downwardly and the ends yoli the lower bar being bent rearwardly and inwardly and upwardly, opposite ends oli the two bars being relatively longer and additionally bent forwardly to terminate adjacent the center et the impact bars, the other ends ot the two hars being` relatively short and secured respectivelytothe longer ends ot the opposite bars, the forwardly bent end portions ol the bara terminating in hooked extremities7 in Vcombination'with a channel member engagl.ingsaid hooked extremities' and means for clamping` the channel member to the central portions of the impact bars.

In testimony whereotl ali-ix my signature.
